Session at a Glance

KOSPI crashes 8% triggering circuit breaker as Broadcom’s AI guidance miss ignites semiconductor rout across Asia.

South Korea’s KOSPI plunged 8.3% on Monday — its worst session since March — tripping circuit breakers after Broadcom’s Q3 AI chip sales guidance of $16 billion missed the $17.2 billion street estimate, reigniting “AI bubble” fears. A hotter-than-expected US jobs report on Friday lifted Fed rate-hike bets, compounding the risk-off mood. Samsung Electronics fell 10% and SK Hynix shed 14% intraday; retail margin debt at a record ₩37.7 trillion amplified forced liquidations.

The damage radiated along the semiconductor supply chain. Japan’s Nikkei lost 3.85% with chip-equipment maker Tokyo Electron down 7.5%. Taiwan’s TAIEX dropped 3.5% as foundry and packaging names sold off. India’s IT services sector buckled — Wipro fell 7.5% on its buyback ex-date colliding with a 4% Nasdaq rout.

Defensive pockets held up: Australia’s CSL rallied 5.75% as capital rotated into healthcare, and NAVER surged 9.2% in Seoul after announcing a multi-year AI infrastructure deal with Nvidia — one of the few names to buck the tape.

Here are the standout movers across Asia-Pacific’s major exchanges for the session of Monday, June 8, grouped by market.

Australia (ASX)

↑ CSL +5.75%

Mega-cap · 97.91 (local)

Why: Defensive rotation into healthcare as global semiconductor and tech names sold off hard; CSL’s biotech-pharma profile attracted risk-off capital fleeing the AI trade.

Pattern: Classic sector-rotation play — mega-cap defensive outperforms on a broad risk-off day. Watch whether the bid holds if tech stabilises; isolated if reversal is swift.

↓ MIN -5.08%

Mid-cap · 67.57 (local)

Why: No clear catalyst beyond broader commodity weakness and risk-off sentiment dragging mining and lithium-exposed names lower alongside the global tech selloff.

Pattern: Mineral Resources has been in a structural downtrend on lithium oversupply headwinds; today’s move extends the trend rather than initiating a new one. Momentum continuation lower.

Hong Kong (HKEX)

↑ 0883 +1.96%

Large-cap · 27.06 (local)

Why: CNOOC outperformed the broader Hang Seng selloff as a high-dividend energy defensive; Q1 net profit rose 7% on higher realised oil prices and 9% production growth.

Pattern: Relative strength in a down-tape session is a positive signal for dividend-yield defensives. Oil names often decouple from tech-driven selloffs — classic sector rotation pattern.

↓ 9988 -2.94%

Mega-cap · 118.8 (local)

Why: Alibaba fell alongside the global tech rout triggered by Broadcom’s AI guidance miss and Nasdaq’s 4% Friday decline; the stock is down 14% over the past month.

Pattern: Momentum continuation lower — Alibaba is trading near its 52-week range midpoint with no clear technical floor. Broad risk-off in China tech, not an isolated event.

China — Shanghai (SSE)

↑ 601857 +3.20%

Large-cap · 10.95 (local)

Why: PetroChina rose as a defensive state-owned energy play amid the tech selloff; China’s oil majors attract domestic institutional capital when growth stocks are under pressure.

Pattern: Relative-strength divergence on a down day — a classic flight-to-dividends rotation within A-shares. SOE energy names often catch bids when the CSI 300 tech cohort sells off.

↓ 600030 -0.93%

Mid-cap · 25.43 (local)

Why: CITIC Securities drifted lower alongside the broader Shanghai Composite decline; brokerage stocks are high-beta to market sentiment and margin-trading volumes.

Pattern: Brokerages are leveraged plays on market activity — a 1.7% index drop with thin catalyst produces modest underperformance. Not a breakout or breakdown; mean-reversion territory.

China — Shenzhen (SZSE)

↑ 000333 +1.42%

Large-cap · 82.85 (local)

Why: Midea Group edged higher as a consumer-appliance defensive with limited AI/semiconductor exposure; its home-appliance and HVAC revenue provides earnings stability in a tech rout.

Pattern: Relative outperformance in a defensive consumer name during a tech-led selloff — part of the broader rotation theme visible across CSL, CNOOC, and PetroChina today.

↓ 300059 -4.32%

Mid-cap · 17.72 (local)

Why: East Money Information fell as an online brokerage and fund-distribution platform — high-beta to market sentiment and trading volumes, both of which cratered today.

Pattern: Similar pattern to CITIC Securities: fintech brokers amplify index moves. ChiNext listings tend to carry higher retail leverage, exacerbating the drawdown. Momentum continuation lower.

Japan (TSE)

↑ 7974 +1.54%

Mega-cap · 7640 (local)

Why: Nintendo bucked the Nikkei selloff as a consumer-entertainment defensive with minimal semiconductor supply-chain exposure; the Switch 2 cycle provides an idiosyncratic growth catalyst.

Pattern: Relative strength on a heavy tape — entertainment and gaming names often decouple from chip-equipment selloffs. Isolated idiosyncratic bid, not part of the broader sector rotation.

↓ 8035 -7.45%

Mid-cap · 5.502e+04 (local)

Why: Tokyo Electron dropped 7.5% as the Broadcom AI guidance miss hammered semiconductor equipment demand expectations globally; the stock is a direct proxy for chip capex spending.

Pattern: Supply-chain contagion from Broadcom’s miss — TEL sits at the heart of the AI capex chain. Momentum breakdown; the stock hit its lowest since January 2026. Watch for capitulation volume.

Singapore (SGX)

↓ O39 -2.09%

Large-cap · 23.44 (local)

Why: OCBC Bank fell as Singapore’s Straits Times Index declined 1.6% in sympathy with the regional risk-off mood; bank stocks tend to weaken on rising recession-probability pricing.

Pattern: Broad regional beta move — OCBC is the STI’s largest component and tracks regional sentiment closely. Not isolated; part of the ASEAN financials basket drifting lower on global risk-off.

South Korea (KOSPI)

↑ 035420 +9.20%

Mid-cap · 2.79e+05 (local)

Why: NAVER surged 9.2% after announcing a multi-year AI infrastructure partnership with Nvidia to build 55MW-to-gigawatt-scale AI factories using the Nvidia DSX platform in South Korea.

Pattern: Catalyst-driven breakout against a collapsing index — rare single-stock strength during a circuit-breaker session. The Nvidia endorsement rerates NAVER as a sovereign AI infrastructure play.

↓ 006400 -11.44%

Mid-cap · 5.03e+05 (local)

Why: Samsung SDI plunged 11.4% as the KOSPI circuit-breaker session crushed high-beta names; the stock already faced headwinds from a paused $3.5B GM battery plant and collapsing EV margins.

Pattern: Structural downtrend accelerated by a macro shock — EV battery margins have compressed to 5.5% gross and the GM JV pause signals demand destruction. Forced liquidation from retail margin calls likely amplified the move.

Taiwan (TWSE)

↓ 3711 -6.41%

Mid-cap · 540 (local)

Why: ASE Technology dropped 6.4% as the TAIEX semiconductor complex sold off in sympathy with the Broadcom AI guidance miss; ASE is a top chip-packaging and testing name in the AI supply chain.

Pattern: Supply-chain contagion — advanced packaging is the bottleneck Broadcom’s miss directly questions. TAIEX -3.5% underperformance in ASE suggests sector-specific de-rating, not just broad beta.

India (NSE)

↑ SBIN +0.27%

Large-cap · 980.3 (local)

Why: State Bank of India eked out a marginal gain as a defensive public-sector banking name; India’s PSU banks draw domestic institutional flows when IT and growth stocks are under pressure.

Pattern: Flat-to-green in a red tape is a relative-strength signal for India’s PSU bank cohort. Minimal move — no breakout thesis, but the rotation into financials-over-IT is a recurring India pattern.

↓ WIPRO -7.53%

Large-cap · 183.4 (local)

Why: Wipro tumbled 7.5% as the stock turned ex-date for its ₹15,000 crore buyback, triggering institutional unwinds, while Friday’s Nasdaq -4% rout crushed Indian IT sentiment broadly.

Pattern: Buyback ex-date + global tech selloff is a compounding catalyst. Wipro hit a fresh 52-week low — momentum breakdown with forced selling from arbitrage unwinds. Watch for post-ex stabilisation.

New Zealand (NZX)

↑ SPK +1.60%

Mid-cap · 1.9 (local)

Why: Spark New Zealand edged higher as a defensive telecom utility; dividend yield attracts capital during risk-off sessions and the stock has limited exposure to the AI/semiconductor selloff.

Pattern: Classic defensive-yield bid on a risk-off day — telecoms and utilities in small markets often decouple from global tech moves. Isolated and low-conviction; not a trend signal.

↓ MEL -2.37%

Mid-cap · 5.77 (local)

Why: Meridian Energy dipped 2.4% in sympathy with the broader NZX weakness; no clear company-specific catalyst — check broader utilities sector tape and NZ wholesale electricity pricing.

Pattern: Low-volume NZX names can gap on thin order books during regional selloffs. The move is modest and likely mean-reverts unless a power-market or regulatory catalyst emerges.

Reading the Session

The exchange-by-exchange breakdown above surfaces both market-specific catalysts and cross-border themes. When multiple exchanges move together, look for a macro driver (USD move, commodity price, risk-on/off shift). Isolated single-exchange moves tend to reflect local earnings, regulatory news, or sector rotation.
